Do electronic devices which are advertised as radar jammers meet the definition of a radar detector in 49 CFR 390.5T?

Guidance: Devices that are said to reflect incoming energy passively or to transmit steadily on the same frequency as police radar units are not radar detectors because they do not detect radio microwaves. Devices that are said to detect and isolate the incoming signal and then to transmit on the same frequency to interfere with the police unit would qualify as radar detectors.
